BURNER.

To all whom it may concern:

Be it known that I, MARGARET ELIZABETH BEEDLE lVILLIAMs, a citizen ofthe United States, residing at Westernport, in the county of Alleganyand State of Maryland, have invented new and useful Improvements inBurners, of which the following is a specification.

My invention relates to a burner designed for use with a jet pipe orsimilar means for furnishing and distributing gas or other ignitiblefluid or agent, and adapted for heating, cooking, laundry or otherpurposes.

While specifically designed as a burner to be used either singly or inseries and with one source of gas supply and with a suitable range, theinvention may be mounted and utilized as a small and convenient stovefor the above mentioned purposes.

In the accompanying drawing, Figure 1 is a perspective view of myinvention. Fig. 2 is a view thereof, mainly in vertical section.

showing a modification hereinafter described. Fig. t is a perspectiveview of a detail. Fig. 5 is a sectional plan illustrating a furthermodification.

A represents the upper or main heatlng plate preferably disk-like inform having inwardly slanting sides a. To this plate 1s bolted orotherwise secured a bottom plate B centrally perforated as at b. Thecentral perforation is surrounded by a boss into which is screwed onemember of a pipe G. This member is connected by an elbow c to ahorizontal pipe C which unites with a gas burner. A gas and air mixer Dof any approved character may be placed as shown.

The upper surface of the plate A is provided with raised portions in theform of ribs or letters a which serve as rests for the vessel to beplaced upon the burner, and to raise said vessel above the upwardlyprojecting elements hereinafter to be described. An annular series ofoutwardly flaring perforations a lead from under the plate A.

Centrally of the plate A is a disk H pivoted at h so as to be capable ofrotation. The disk H is provided with inclined apertures it which maybe'made to register with the inner series of perforations c in the plateA. The disk H is also furnished with raised portions, in the form ofribs or letters, similar to those provided for the plate Specificationof Letters Patent.

A and for the same purpose. They may also be used in lieu of a knob orlug for rotating the disk. At the underside of the plate A, and integraltherewith, is an openbottomed circular partition or cylinder A, havingradlal openings a and which cylinder rests upon the bottom plate B. Anupwardly turned flange b fits, against andmakes a joint with thecylinder A so that the plate A, bottom plate'B and cylinder formpractically one member. Outside of the cylinder A, and surroundmg thesame, is a cylindrical and rotary sllde or gate E, shown particularly inFig. 4c, whlch revolves around the circular partition or cylinder A andis provided with a lug or lugs c which project through segmental slotsin the plate A so that the slide E may be rotated by the use of anysuitable instrument, as a stove lifter or the like. The rotary slide Eis provided with radial openings e which at the proper time registerwith those a of the cylinder A. Concentric with the inner rotary slideor gate E, thus described, is a similar one F which,

except as to size, may be also represented by i Fig. at, and whichrevolves around a circular partition or cylinder F forming a part of theupper section or plate A, and also resting upon the bottom plate B. Thecylinder F the latter being provided with openings f similar to thosealready described, and

which at the proper time are made to register with the correspondingopenings in the cylinder F. The second rotary slide F is furnished witha lug or lugs 9 extending through segmental slots in the plate A, asshown particularly in Fig. 1. These slots are covered by flanges toprevent the escape of gas, such flanges being shown by Z in Fig. 4. Thearrangement of these rotary slides is clearly indicated in Fig. 3, theleft hand portion of which shows an annular slide G having a functionsimilar to that of the disk H. A stop for this annular slide is showniacts with a cylindrical and rotary slide Patented Aug. 1, 1911.

has a tendency to draw to the center. The use of too much heat at thecenter is therefore checked or prevented by one or the other or both ofthese devices as conditions may require.

t will be understood that under the construction described, and byclosing the 1nner rotary slide or gate, gas will be admltted to thecentral cylinder or region only of the burner, the rotary slide being soturned or adjusted that the openings have no communication with theimmediately surrounding region, and that the flame will pass through theinclosed inclined. openings it of the upper plate A, the disk H being soadjustedor turned that its perforations reglster with those of saidplate. The projections consisting of the ribs or letters upon the saiddisk extending above the head of the central pivot and lugs e, a smallvessel may be placed upon the disk and heated; and, as will beunderstood, only a limited portion or head of gas will be needed for thesmall amount of heat required when only this small area of the burner isutilized. Should a greater amount of heat be needed, the neXt and largerrotary slide or gate is turned so that its openings register with thoseof the corresponding cylinder, and it will be understood that in thiscase the still larger rotary slide or gate is so adjusted with referenceto its openings and that of its cylinder that communication is shut offfrom the outer space or region of the burner. If the greatest amount ofheating surface is required the outermost rotary slide or gate isopened, in which case there will be free communication from the centerto the outermost extremity of the burner. I do not limit myself to thenumber of partitions and slides or gates, as the number may be made tocorrespond with the requirements. It will thus be seen that theconsumption of gas is only needed in proportion to the amount of heatingto be accomplished. Heretofore, so far as I am advised, a separate valveand air mixer has been used for each burner, whereas in accordance withmy invention but one is employed.

I prefer to give a sloping shape to the sides of the plate A in orderthat the burner may be readily inserted within the firebox of anordinary range, and also to make the size as small as possible. It willbe seen that two or more of such burners as constitute my invention maybe used in groups fed by a common gas and air mixer.

While my invention is here termed a burner, and may be used with asuitable stove or range, it may be furnished with legs or a stand, andthus become a convenient and economical table stove. However used ormounted, it is applicable for heating, cooking, laundry or other use.

One of the main advantages of my invention is that heat is only used inaccordance with the special requirements, whereby gas is saved.

lVhile I have described the slides or gates as rotary they may be hingedto the cylinders as indicated in Fig. 5. Referring to this figure, twocylinders are shown, the inner one by E and the outer one by F. Thehinged gate for the inner cylinder is inclicated by E and that for theouter one by F they being hinged at e and f respectively. The openingsthrough the cylinders are shown by e and f respectively. The movement ofthe hinged gates E F is guided by means of pintles e, which run insegmental grooves or slots 6 f.

lVhile I have preferably shown my burner as of circular form throughout,it is obvious that it may be of other shape, the only requisites beingthat the top plate shall be provided substantially throughout its areawith combustion apertures, that each interior section or compartmentshall be in communication with certain of such apertures, that thedevice shall be capable of receiving gas at an initial point, and thatby the manipulation of slides, plates or the like, gas shall beoptionally distributed to a larger or more extended area, and suchmodifications of construction as will carry out this essential principleof operation are considered as within the scope of my invention.

Having thus described my invention, 1 claim z- 1. In a gas burner, abody comprising a top plate provided with perforations for thecombustion of gas, a plurality of compartments the partitions of whichhave openings, said compartments each communicating with certain of theperforations in the top plate, and a series of adjustable slides orgates furnished with openings adapted to register with those of saidpartitions, combined with a single source of gas supply leading to oneof said compartments, whereby one of the same may be used singly or withothers of the pluralityof compartments, substantially as set forth.
